sPmNG-'LUBRCATING DEVICE.

Application led July 20, 1922. Serial No.'576,326l

ticles and has for itsv object to provide aA lubricant 'retainingmaterial which may be readily, easily and economically wrapped or encircled about the entire spring or any vportion thereof so that dust, dirt and water may be prevented from retardi'ng the resiliency thereof, and so that the spring may always be well lubricated.

Another object is-to provide a flexible, yieldable spring wrapping device of simple and cheap construction for the purpose of insuring lconstant; lubrication of the spring.

Other objects of the invention will be apparent as the details of the inventionare disclosed and illustrated in the accompanying drawing forming a part of the application. l

In the drawing:

Figure 1 is ya side elevational view of an elliptical vehicle spring showing the manner in which my invention may be applied;

Figure 2 is a cross sectional View of one type of my invention-as applied to a leaf spring and secured thereto by means of nails;

Figure 3 is a fragmentary sectionalview of the device; Figure 4 is a cross sectional view of a leaf spring provided with a modified form of the invention;

Fig. 5 shows a further modification whereby theabsorbent and metal bands are stitched to ether to prevent slippage therebetween. igure 6 is a top plan view of a section of spring equipped with onel form of the iuvention, shown in'section in Figure.

In carrying out my invention I provide a band of absorbent material of any desired width as indicated by numeral 5 in Fig. 3, having a center core or band of the same width'or less 6 composed of any soft flexible metal. This metal core while being of yieldable material still possesses sufficient strength to serve asa binding means for holding the 'absorbent material in' its position upon the spring and at the same time permits the device to be wrapped around and snugly f it the irregular contour thereof.

While the metal core is sufficient of itself to retain the device in positionon the spring, nevertheless, in order to prevent any possibility of' displacementthe overlapped ends of the device as illustratedin Fig. 2, may be nailed or otherwise secured. The nails 7 will readily penetrate the soft metal core and upon contact with the hard metal spring S will bend` and clinch, thus sealing the device in position.

Figure 4f shows a modified formof wrapping the spring wherein I provide a band of absorbent material 8 with an outer band of soft metal 9 upon which at spacedintervals are arranged slots 1() and ears 11 capable of being depressed into the absorbent material as a means of clinching the device securely upon the spring. The slots 10 and the openingscaused by the depression of the ears 11 also provide means by which the absorbent material may besupplied with oil .for the lubrication of the spring leaves. u

One form of the invention is shown by Fig. 5 which shows a cross sectional view of a vehicle spring S with a spring wrapping comprising van absorbent strip against nthe spring and an outer strip of ductile metal and adapted to be stitched together as indicated at 12. The absorbent and metal strips should be stitched together before the device is wrapped about the spring.

The bands of absorbent material and soft flexible metal may be applied with one or more wrappings at righty angles `to the spring and may cover the entirespringr or comprise only a single wrapping as shown by Fig. 1, wherein theupper part of the spring is shown wrapped with a series of separate sections 15' any one of which may be replaced without disturbing the lother sections.' The' lower left portion of the spring shows my invention indicated by numeral 16 wrapped spirally and at 17 is lshown a single wrapping of the device. Any

manner of wrapping as illustrated may be employed to secure the best results under varying conditions. When the entire sprin lis covered the device should be wrappedspirallyand :when only partly covered the d evice should encircle the spring once at ught angles thereto with sulcient overlapping of the ends to permit clinching or nailinif desire hen a single section is a plied to the Y lower half of the spring it Wi l be unnecessary to anchor the device in any manner since tendency to drift would be toward the thick portion of the spring which would thereby preventslippage.

p provided in the device permit further lubrication of the sprin and replenishment of the oil to the absor ent material Whenever desired.

l,While several modifications of the invention are 'shown in the drawing other 'arrangements for securing the device to the spring may be adopted or the invention may be utilized for other purposes without departing from the spirit thereof. The metal band may be perforated as shown in Fig.

A 6 so that the absorbent material may be `stitched' or laced thereto toA form a rigid connection.l

-I claim l l. A lubricating device of the character described ada ted to be- Wound spirally about a vehic e spring and consisting of The openings v Lasa; 1e

spacedfapartat layers of absorbent material, and a soft' or ductile layer of metal 4ot -approximately "the same Width as the absorbent layers and arranged between the same.

2.v Alubricating deigice adapted to be Wound spirally about a vehicle spring and comprising a central soft or ductile` metal plate fiat in cross section and disposed intermediate absorbent plates'or layers, and means holding the metal plate and absorbent layers together., v

3. A spring cover comprising a flat strip of absorbent material, a fiat strip of soft or ductile metal itted against the absorbent strip, and ears .projecting from they metal strip into the absorbent stri-p for holding the strips together. l

4:. spring lubricating device comprising flat stri s of absorbent material and of soft or ducti e metal approximately of the same Width and fitted face to face, means for securing the flat strips together, the metal plate being provided with perforations for the passage of securing means, the secured strips being adapted to be Wrapped around the vehicle spring or any`portion thereof.

5. A vehicle leaf spring lubricating device of indefinite length adapted to be spirally Wound about-the spring and composed of absorbent and reinforcmg layers of approximately equal Width, and secured face to face.
